Allen Crabbe Knee Injury

Leave a comment

The Brooklyn Nets professional basketball player, Allen Crabbe has not played since December 12, 2018  due to a right knee injury that occurred during a game against the Philadelphia 76ers. His right leg got tangled with 76ers center Amir Johnson, while taking a shot.  This knee injury was particularly frustrating to Allen, given that  it occurred during his first game after coming back from a left ankle sprain that  occurred in the pre-season.

It’s difficult to tell from media reports what the problem is with his knee.  One report described it as inflammation of a “fat pad”, but that’s not a common knee injury or diagnosis.

Media reports describe removal of the “excess fluid” out of his swollen right knee. There is almost never a good reason for doing this.  It’s difficult to make sense of what is going on.

Adding to the puzzlement, according to his coach, Crabbe will not have  surgery.

It is not clear how many more games Allen will be missing and whether he will be back any time this season.

Boban Marjanovic’s Knee Contusion

Leave a comment

Boban Marjanovic, recently traded from the LA Clippers to the Philadelphia 76ers, was carried off the court with knee pain late in the game against the Pelicans Monday, February 25, 2019. The injury happened during a defensive play where Marjanovic’s leg was twisted and tangled up with New Orleans’ Cheick Diallo as the two were going for the ball. Boban was not able to get back up and he seemed to be in extreme pain.

He later had an MRI that showed only a bone bruise (contusion) and a minor ligament strain. There was no injury to the anterior cruciate ligament or other major injury.  

This injury is similar to the Boston Celtics rookie Robert Williams knee to knee collision that happened during the first game of the Summer League on July 6th, 2018.  Treatment for a bone contusion is supportive and nonspecific.

Boban is expected to return to action before the end of the regular season.

Zion Williamson Sprained Knee

Leave a comment

On Wednesday, February 20th, 2019, Duke’s superstar freshman suffered a right knee sprain thirty seconds into their game against rivals UNC. Dribbling the ball early in the game, Williamson planted his foot to change directions. His shoe panel ripped and his left foot popped free of his shoe. He immediately clutched his knee. Williamson did not return for the remainder of the game.

After the game, Blue Devils coach Mike Kryzewski stated Williamson sustained a “mild knee sprain,” but the knee was stable. What this means is this is likely an injury to the medial collateral ligament, a ligament that heals quickly on its own, rather than the anterior cruciate ligament, which doesn’t heal and usually leads to surgical reconstruction in an athlete that pivots (twists) a lot. A knee sprain is a partial or completed tear of a ligament. A ligament is a structure that connects and stabilizes two bones where they meet at a joint.

Treatments might include ice and modification of activity, limiting stress on the ligament but maintaining motion. Sometimes a brace is used for comfort.
